edge-bench-rs: libdeflate for chunks, memchr for lines and tabs

libdeflate inflates a chunk whole, in half the time of zlib-rs (1.09 ->
0.51 s per boneless range); memchr finds line ends and tabs with SIMD.
The per-article timers are gone. Boneless 2026 ~700k headers/s, ath 2013
~920k; all three captures still identical to the TypeScript.
